DETAILED DESCRIPTION

An exemplary autonomous vehicle includes a passenger compartment and atleast one seat located in the passenger compartment. The seat can bemoved from a front-facing position to a rear-facing position when thevehicle is stationary or while the vehicle is operating in an autonomousmode. In some implementations, the seat may include a bench seat with abottom portion and a back portion. The bench seat may be configured tomove from a front-facing position to a rear-facing position by movingthe back portion toward a front of the passenger compartment. Moreover,the seat may be stowed under the instrument panel in certainimplementations. The vehicle may further include autonomous drivingsensors and an autonomous controller that receives signals generated bythe autonomous driving sensors (e.g., sensors for driving the vehicle inan autonomous mode) and controls at least one vehicle subsystem tooperate the vehicle in autonomous mode according to the signalsreceived.

The FIGS. illustrate exemplary views of an autonomous vehicle 100 withreconfigurable seats. The vehicle may take many different forms andinclude multiple and/or alternate components and facilities. While anexemplary vehicle is shown, the exemplary components illustrated are notintended to be limiting. Indeed, additional or alternative componentsand/or implementations may be used. Moreover, the components shown inthe FIGS. are not necessarily drawn to scale.

As illustrated in FIG. 1, the vehicle 100 includes a passengercompartment 105 located in an interior of the vehicle 100. The passengercompartment 105 may include any part of the vehicle 100 where passengersmay sit while the vehicle 100 is operating. In addition, the passengercompartment 105 may include seats 110 and controls that allow a driverto control operation of the vehicle 100. Examples of controls mayinclude a steering wheel 115, an accelerator pedal 120, a brake pedal125, etc. Although illustrated as a sedan, the vehicle 100 may includeany passenger or commercial vehicle such as a car, a truck, a sportutility vehicle, a taxi, a bus, etc.

FIG. 2 is a block diagram of an exemplary system 130 that may be used inthe autonomous vehicle 100. As shown, the system 130 includes a userinterface device 135, autonomous driving sensors 140, an autonomous modecontroller 145, and a seat motor 150.

The user interface device 135 may be configured to present informationto a user, such as a driver, during operation of the vehicle 100.Moreover, the user interface device 135 may be configured to receiveuser inputs. Thus, the user interface device 135 may be located in thepassenger compartment 105 of the vehicle 100. In some possibleapproaches, the user interface device 135 may include a touch-sensitivedisplay screen.

The autonomous driving sensors 140 may include any number of devicesconfigured to generate signals that help navigate the vehicle 100 whilethe vehicle 100 is operating in an autonomous (e.g., driverless) mode.Examples of autonomous driving sensors 140 may include a radar sensor, alidar sensor, a camera, or the like. The autonomous driving sensors 140help the vehicle 100 “see” the roadway and the vehicle surroundingsand/or negotiate various obstacles while the vehicle 100 is operating inthe autonomous mode.

The autonomous mode controller 145 may be configured to control one ormore subsystems 155 while the vehicle 100 is operating in the autonomousmode. Examples of subsystems 155 that may be controlled by theautonomous mode controller 145 may include a brake subsystem, asuspension subsystem, a steering subsystem, and a powertrain subsystem.The autonomous mode controller 145 may control any one or more of thesesubsystems 155 by outputting signals to control units associated withthese subsystems 155. The autonomous mode controller 145 may control thesubsystems 155 based, at least in part, on signals generated by theautonomous driving sensors 140.

The seat motors 150 may be configured to control the position and/ororientation of one or more seats 110 inside the passenger compartment105. Each motor 150 may be associated with only one seat 110.Alternatively, a single motor 150 may be used to move multiple seats110, including an entire row of seats 110. The motor 150 may operate inaccordance with control signals output by the user interface device 135.For example, the user interface device 135 may receive commands from thedriver or another passenger indicating a desire for one or more seats110 to adopt a particular configuration. The motor 150 may automaticallyadjust the seats 110 to the desired configuration. Examples of differentpossible seat 110 configurations are described in greater detail below.For example, the motor 150 may cause the seat 110 to pivot, fold,unfold, slide, recline, etc.

Referring now to FIGS. 3A-3B, the passenger compartment 105 includes anumber of seats 110 and a center console 160. The seats 110 may includeone or more bucket seats, captain's chairs, bench seats, split benchseats, or the like. Moreover, the seats 110 may be separated into rows,including a first row, a second row, and in some instances, a third row(see, e.g., FIG. 8). The first row may generally refer to the rowclosest to the front of the vehicle 100. One or more seats 110, such asthe seats 110 in the first row, may be moved from a front-facingposition to a rear-facing position while the vehicle is stationary orwhile the vehicle is moving to allow the passengers in the vehicle 100to face one another when the vehicle 100 is operating in the autonomousmode.

One way to move the seats 110 from the front-facing position to therear-facing position may be to rotate the seat 110. The seat 110 may berotated about an axis 175A that extends generally perpendicularly from afloor of the vehicle 100 and through a center of the seat 110. Rotatingthe seat 110 may occur automatically when the vehicle 100 is operatingin the autonomous mode or while the vehicle is parked. Moreover, theseat 110 may be rotated manually by, e.g., removing and repositioningthe seat 110 or spinning the seat 110 about the axis 175A.

Alternatively, one part of the seat 110, such as a back portion 165, maypivot relative to another part of the seat 110, such as a bottom portion170. FIGS. 3A-3B show how the back portion 165 may pivot relative to anaxis 175B defined by the bottom portion 170. That is, the back portion165 of the seat 110 may include one or more arms 180 that are pivotallyattached to a frame 185 of the bottom portion 170. When the back portion165 has been pivoted to a rear-facing position, the bottom portion 170may become angled toward the front of the vehicle 100 as shown. Themovement of the seat 110 from the front-facing position to therear-facing position, and vice versa, may be actuated manually or by themotor 150 (not shown in FIGS. 3A-3B) when the vehicle 100 is stationaryor operating in the autonomous mode. Different ways of reorienting theseats are described for illustrative purposes only. Other suitable waysto reorient the seats while the vehicle is stationary or moving inautonomous mode may alternatively be used.

A locking mechanism (not shown) may prevent the seat 110 from beingmoved to the rear-facing position, and vice versa. The locking mechanismmay be manually unlocked by the user or automatically by, e.g., themotor 150 or another device. The original position of the seat 110 isshown in FIG. 3A, and FIG. 3B shows one of the seats 110 in a rearwardposition.

The console 160 located between the two front seats 110 may beconfigured to slide toward the front of the vehicle 100 when one or bothseats 110 in the front row are in the rear-facing position.Alternatively, the console 160 may slide toward the back of the vehicle100 to a position between the first and second rows of seats 110. Thisway, when one or more seats 110 in the first row are oriented in arear-facing position, the center console 160 may act as a tableavailable for passengers in either the first row and/or second row touse. The rearward movement of the central console 160 may alsofacilitate the reorientation of seats 110, which move between forwardand rearward orientations by rotational movements. In other words, theentire console 160 may move toward a center of the passenger compartment105 to allow one or more of the seats 110 to change orientations. FIG.3A shows the console 160 in its original position while FIG. 3B showsthe console 160 moved away from the front of the vehicle 100.

Referring now to FIG. 4, an airbag 190 may be located in the passengercompartment 105 between the first and second rows of seats 110. Theairbag 190 may be deployed as a result of a collision while the vehicle100 is operating in the autonomous mode and/or in a non-autonomous mode.The airbag 190 may be shaped such that a single airbag may be used forall passengers, including rear-facing passengers sitting in the firstrow and front-facing passengers sitting in the second row or multipleairbags may be used. Although the seats 110 shown in FIG. 4 areseparate, the seats 110 may include bench seats or split bench seatsthat form an entire row, as shown in FIGS. 5 and 6.

FIGS. 5 and 6 illustrate a passenger compartment 105 with two rows ofbench seats 110. In FIG. 5, the first row is arranged in a rear-facingposition and the second row is arranged in a front-facing position.Although not shown in FIG. 5, the front bench seat 110 may include arms180 and a frame 185 similar to those shown in FIG. 3 for moving thefront bench seat 110 into the rear-facing position. Therefore, the backportion 165 of the bench seat 110 may be configured to pivot about theaxis 175B (see FIG. 3) defined by the bottom portion 170 to move intothe rear-facing position. Pivoting the back portion 165 about the axis175B and toward the front of the passenger compartment 105 may cause thebench seat 110 to be arranged in the rear-facing position while pivotingthe back portion 165 about the axis 175B and away from the front of thepassenger compartment 105 may cause the bench seat 110 to be arranged inthe front-facing position (shown in solid line in FIG. 6). Moreover, thesteering wheel 115 may move toward the instrument panel 195 to make roomfor the front seats 110 to move toward the instrument panel 195 toincrease the leg room between the front and second row seats 110 whenthe front seats 110 are facing rearward.

Alternatively, with reference to FIGS. 6-8, the front row seats 110 maybe folded toward the front of the passenger compartment 105 aboutanother axis 175C defined by the bottom portion 170 of each seat 110.The seats 110 may be folded and, e.g., stowed under the instrument panel195, which may be located at the front of the passenger compartment 105.In one possible approach, the folded seats 110, including the driverseat and the front passenger seat, may slide along rails 200, located onthe floor in the passenger compartment 105, toward an area underneaththe instrument panel 195. FIG. 6 illustrates an example where the frontrow includes a bench seat 110 and FIGS. 7 and 8 illustrate exampleswhere the front row includes adjacent bucket seats 110 (i.e., a driverseat and a front passenger seat). The motor 150 (see FIG. 2) may be usedto fold the seats 110 and/or move the seats 110 to the location underthe instrument panel 195. Moreover, the motor 150 may return one or moreof the seats 110 to their original positions and/or orientations.

To accommodate the seats 110 under the instrument panel 195, one or morecomponents located in the passenger compartment 105, such as theaccelerator pedal 120 and the brake pedal 125 (see FIG. 1), may be movedfurther toward the front of the passenger compartment 105. Moreover, thesteering wheel 115 may move to make room for the driver's seat 110 toslide under the instrument panel 195. In some possible approaches,another row of seats 110, such as the second row or third row (see FIG.8), may move forward when the seats 110 in the first row are stowedunder the instrument panel 195. Alternatively, or in addition, the thirdrow may, e.g., recline so that the back portion 165 and bottom portion170 are substantially aligned with one another.
